Admitting that his power is inadequate to battle the Anti-Monitor, he sets course for the world of a more powerful being. On Earth, the Anti-Monitor's visage is seen in the skies all over the globe. He repeats that the Earth is now in the anti-matter universe. His past victories over positive universes are meaningless, he says, because of the super-heroes' efforts to stop him. When he lists Supergirl and the Flash as casualties, Kid Flash demands to know what has happened.
The Supermen scan the globe and watch the populace panicking. Harbinger appears, and teleports them to a chosen destination, then gathers Dr. Light from Japan, leaving Sunburst to defend the island. When Dr. Light states that she caused Supergirl's death, Harbinger replies that the battle had already killed Supergirl, and that the Anti-Monitor's final attack merely gave her a swift death. In the skies, the darkness splits into a million shadow demons, which begin an all-out attack on humanity, and the super-heroes mass to resist them. The Global Guardians team with other heroes to free their native lands from the threat, but the demons' numbers seem endless. The Phantom Stranger summons Dr. Mist to help revive the Spectre who lies comatose. Below, Harbinger has gathered a large group of heroes, along with Pariah and Alex, to lead a final assault on their nemesis. Alex creates a bridge between universes, and they depart near Apokolips.

Suddenly, an image of the Flash appears to him—the last one Barry cast before his death. Wally follows the afterimage to where an insane Psycho-Pirate clutches at an empty uniform. Kid Flash knocks him out, and realizes that Barry Allen is truly dead when Lady Quark finds his ring. Pariah informs them that a great concentration of evil lies before them.
